Apprenticeship
Most would-be Wizards have their magical awakening at 15-20, and it's rare for it to happen outside 10-25. The first third of their approximately ten to twelve year Apprenticeship is the Junior Apprenticeship, spent developing control over the ability to touch the Winds. For some people this means learning how to reach out and touch it, for others it's learning how to stop. They cannot leave the mono-Wind environment of the Colleges without risking Dhar poisoning. They usually get a Master in the middle third of their Apprenticeship when they reach regular Apprentice, which is when they start learning how to actually do things with magic instead of learning how not to be killed by magic. Most spend this inside the College, though it can be spent at any College-controlled location, and they still rely on mono-Wind environments for practice and learning. In the final third of their Apprenticeship, Senior Apprentices have enough control and ability that they can be allowed to leave College property of their own accord. Practically every Senior Apprentice will have a Master, as it's the level when they can pull their weight and properly assist their Master. Some of them join their Master on their missions or get sent on simple assignments, some of them go adventuring on their own, most just use it to explore Altdorf.
